Step Ⅳ Using structures (Workbook)

T: First let's look at the pictures on page 65 and try to talk about them using the -ing form and the past participles. I'd like you to talk about each picture by asking and answering the questions and try to use complete sentences so that you may know the relationship between the verb form and the exact thing it explains, for example, as to the first picture, one may ask.

Show the following.

S: What are the boys doing?

R: They are looking at the bulletin board showing the result of the football match.

S: What is disappointing?

R: The score of their team is disappointing to them.

T: Now, work in pairs and practise talking about the pictures.

Check the answers. And then ask the students to do Exercise 2.
